MOTOR AND STOP MECHANISM FOR AUTOGRAPHIC REGISTERS.

Specification of Letters Patent.

Patented Oct. 31, 1916.

Application filed February 7, 1916. Serial No. 76,505.

To all whom it may concern Be it known that I, Ann. C. V. MALM, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Motor and Stop Mechanism for Autographic Registers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to autographic registers.

1 The object of the invention, broadly .stated, is to provide an organization of mechanism by which this class of registers can be motor-operated, the medium for driving the motor being preferably electricity.

The preferred construction and organization of mechanism are disclosed in the accompanying drawings and described in this specification, as one embodiment of the invention.

Among the special features are devices which, when the motor is cut off from the register, will automatically retard the momentum of the moving parts of the register, to prevent shock, and to enable the definite stopping of the mechanism at a given point coinciding with the limit of the paper-feeding movement of the register.

In the accompanying drawings, Figure l is an elevation of the mechanism, partly in section; Fig. 2 is a sectional side elevation on the line 22 of Fig. 1, looking in the direction'of the arrows; and Fig. 3 is a plan view of the mechanism with parts in section -on the line 33 of Fig. 1.

In the embodiment of the invention here shown the register casing is indicated by the numeral 1. Within this casing is mounted a shaft 2 having thereon spaced pin wheels 3 and 4 which project above the support 5 on which the webs of paper to be fed lie. Above the support 5 is the register lid 6 having means 7 thereon to hold the webs of paper in engagement with the teeth and against the support. Secured to the shaft 2 is a gear 8 which meshes with a gear 9 sultably journaled within the casing, the gear 9 meshing with a gear 10 fixed to a shaft 11 suitably journaled within the casing 1. The mechanism above described is the usual mechanism found in registers of this nature and upon the outer-end of the shaft 11 is usually located the crank handle for operating the same. The invention herein described is adapted to be attached to the above described-mechanism.

A suitable source of power 12 which, in the present instance, is an electric motor, is mounted within a frame 13 adjacent the easing 10f the register. A driving shaft 14: having a pinion 15 thereon is arranged to be rotated by the motor. A system of double compound gearing to reduce the speed of the motor when applied to the feeding mechanlsm is interposed between the pinion 15 and the feeding mechanism. This system of gearing, as here shown, although any other type of transmission may be used, comprises a gear 16 meshing with the pinion 15 and fixed to a suitably'journaled shaft 17. Motion is transmitted from the shaft 17 through a gear 18 fixed thereto to a gear 19 fixed to the shaft 20. The shaft 20 has fixed thereto a gear 21 which meshes with a gear 22 located at the end of the shaft 11. This gear 22 takes the place of the ordinary handle on registers of this nature.- Mounted adjacent the register upon the upper portion of the frame 13 is a'pair of spaced blocks of insulating material 23. Metallic contacts 24 are suitably fixed to the bottoms of these blocks of insulating material and project inwardly toward each other. Conducting wires 25 lead from these contacts and are suitably connected to the motor 12. Mounted above the casing on the outside thereof is the usual button switch casing, indicated at 26. Slidably mounted within said casing 26 is an insulated button 27 having at its lowered end an insulated member 28 carrying contact members to which are connected in any suitable manner the conducting wires 29. These wires can be connected to any source of electrical energy, such as the socket of a lighting system. The button 27 is extended below the member 28, as shown at 30, and comprises an abutment thereon, as shown at 31, a notched portion, as shown at 32, and a wedge, as shown at 33, the purposes of which will be described hereinafter. A bracket 3 1 projects downward from the upper portion of the frame 13, this bracket comprising a pair of spaced arms, 35 and 36. through which the extending portion 30 projects. The upper portion of the bracket forms a shoulder 37 and this shoulder with the collar 31 constitutes a pair of abutments between which a spring 38 is located to keep the circuit normally open. A lever 39 is pivoted between its ends to the end of the arm 36, as indicated at 40. The lower end of this lever is located within the space between the arms 35 and 36 and a spring 41 connects the same to the bracket, the spring exerting a tension upon the lower end of the lever to move the same rearwardly a ainst the extending portion 30, as shown in Fig. 1. The upper end of the lever 39 lies closely adjacent to the outer face of the gear 22. This gear has mounted thereon a cam lug, as indicated at 42. A pin 43 is slidably mounted within the lower arm 35 of the bracket 34. This pin has an inclined surface 44 coiiperating with the wedge-shaped end 33. The pin is normally held in projected position by a spring 45, the projecting end of the pin abutting against the surface ofthe gear 22. In the position shown in the drawings th1s pin is projecting into a hole 46 in said gear to lock the entire mechanism against movement. Fixed to the shaft 2 intermediate the pin wheels 3 and 4 is a friction pulley 47. A pair of friction bands 48 extend both above and below the friction pulley 47. These bands are held in a clamping device 49 attached to a fixed shaft 50 mounted on the casing of the register. The tension of the straps can be adjusted by means of a' screw 51 which connects the ends of the straps opposite to the clamping device.

The operation of the mechanism is substantially as follows: Itis generally customary to feed a definite amount of paper at each operation. In the present case a com-- plete revolution of the gear 22 feeds the required amount of paper and it is essential that the operation of the device ceases at the instant that a complete revolution is made. When it is desired to operate the machine the button 27 is depressed and this will cause the inclined surface 33 to engage the inclined surface 44 and retract the pin 43 from the hole 46. The mechanism is thereby unlocked. Further movement of the button 27 closes the circuit and the motor begins to rotate. The rate of rotation of the motor, of course, is relatively very great and a reducing mechanism is interposed between the same and the feeding device. This mechanism will cause the rotation of the pin wheels at the proper rate. The retarding device does not unduly retard this tates the cam lug will engage the upper end I of the lever, causing the same to move back,

the lower end of the levermoving forward It will be seen that a very small retarding force at this point on account of the leverage through the reducing gear will rapidly retard the motor and the adjacent mechanism. Immediately after this retarding force has become effective the hole 46 comes in alinement with the pin 43, the pin thereby entering the hole and locking the mechanism against further movement. It should be noticed that the cam lug 42 and the hole 46 are so located that the pin will not enter said hole after the current has been shut off by the engagement of the cam with the lever until the retarding device has sufficiently retarded the mechanism so that there will be no danger of shearing or breakmg the pin or any of the other parts. The retarding device including the friction pulley and the band can be so regulated as to properly time the retarding effect so that the hole will come into alinement with the pin at the proper moment. Attention is called to the ease with which this mechanism can be operated. A single pressure upon the button 27 is all that is necessary. The motor will then rotate the feeding mechanism steadily and quickly, the button 27 remaining locked in position until nearly a complete revolution is made. The cur rent is then shut off automatically and the retarding device comes into operation to retard the mechanism. After the mechanism has been sulliciently retarded and at the instant the necessary amount of paper has been fed the mechanism locks automatically with a minimum stress being exerted thereon.

In the embodiment of the invention here shown the cam lug and hole to receive the locking device are situated upon the gear 22 which takes the place of the handle, as mentioned above. By this arrangement the present improvement can be applied very easily to the types of registers now in use, but it is to be understood, however, that the invention is not limited to this location of the cam lug and hole. The locking device and the automatic feature for opening the circuit can be applied to any part of the mechanism.

While I have shown and described one embodiment of the invention it will be understood that this has been chosen for the purposes of illustration only, and that I do not desire to be limited to the details of 5 construction shown and described, for obvious modifications will occur to a person skilled in the art.
